What are the commonly used cemented carbides? What are their performance characteristics and uses?

Cemented carbide is a composite material composed of metal powder, binder and hard phase. The hard phase is usually carbide, nitride, boride, etc., which has high hardness and good wear resistance. The binder plays a role in connecting the hard phase. Commonly used binders include cobalt, nickel and other metals.

Carbide has high hardness, good wear resistance and high temperature stability, and is widely used in mechanical processing, mining, oil drilling and other fields.
Commonly used cemented carbide types and performance characteristics
1. Tungsten cobalt alloy
Tungsten carbide alloy is a hard alloy with a tungsten content generally above 80% and a cobalt content between 10% and 20%. Tungsten-cobalt alloy has high hardness, good heat resistance and corrosion resistance, as well as excellent cutting performance. Tungsten-cobalt alloy is widely used in mechanical processing, mining, oil well drilling and other fields.
2. Tungsten titanium and tantalum alloy
Tungsten titanium-tantalum alloy is a newer cemented carbide with high hardness and wear resistance, as well as good corrosion resistance and high temperature resistance. Tungsten-titanium-tantalum alloy is suitable for cutting and drilling under high temperature and high pressure. It is also widely used in high-tech fields such as aviation, aerospace, and national defense.

3. Tungsten ferroalloy
Tungsten ferroalloy is a hard alloy mainly composed of tungsten and iron. Tungsten ferroalloy has high hardness and wear resistance, and its performance is even better at higher temperatures. Tungsten ferroalloy is widely used in mining, mechanical processing, chemical industry and other fields.
There are many types of commonly used cemented carbide, but the main ones are tungsten-cobalt alloy, tungsten-titanium-tantalum alloy and tungsten-ferroalloy. These three types of cemented carbide have high hardness and good wear resistance, and are widely used in mechanical processing, mining, oil drilling and other fields. In addition, with the development of science and technology, the application scope of cemented carbide will continue to expand.
